Nioxin System 4 Advanced Hair Loss Serum for Damaged/Colored Hair
Nioxin System 4 Advanced Hair Loss Serum for Damaged/Colored Hair is rated 4.1 out of 5 by 44.

Rated 5 out of 5 by from Bounce [This review was collected as part of a promotion.] My hair after using it for a month seemed thicker and more full. Not sure if it helped the grey hair or not. But it feels different. Having the three products I think has made a difference.

Rated 5 out of 5 by from Hair serum [This review was collected as part of a promotion.] I now love using these products, they was given to me as part of a review package and I have to say I'm impressed with the serum that I never used before

Rated 5 out of 5 by from Leaves hair thicker and stronger. [This review was collected as part of a promotion.] I have been using the Nioxin System 2 Hair Loss Serum for Natural Hair with Progressed Thinning for around 6 weeks now, I use it 3 or 4 times a week after washing and conditioning my hair, I feel there is definitely a lot of improvement in my hair as it feels a lot thicker and I'm not noticing many bald spots anymore. The serum is a leave-in formula that is a lightweight foam mousse, it nourishes the hair and scalp. You just give the bottle a good shake, pump some out, the amount would depend on the amount of hair that you have, then massage the serum onto your head, there's no need to rinse it off. It doesn't feel sticky or greasy and leaves my hair feeling thicker and smoother. The bottle, with a pump top, is a good size, the serum lasts a long time as you don't need to use a lot for it to be effective.

Rated 5 out of 5 by from Noticeable fullness in thinning areas [This review was collected as part of a promotion.] After a few uses, my hair felt thicker in areas that had thinned out. The lightweight foam absorbs easily and adds volume without residue. Easy to apply but be careful if you have eczema or scalp sensitivity.

Rated 1 out of 5 by from Wouldn't recommend [This review was collected as part of a promotion.] Product left my hair dry and brittle with no visible new growth. Disappointed and wouldn’t recommend for thinning hair. I wouldn't purchase this product

Rated 4 out of 5 by from Effective when using with shampoo & conditioner [This review was collected as part of a promotion.] The serum is easy to use & work through my hair, and I love how quickly it absorbs. The scent is nice to use. Product so far has been pretty effective look forward to using it for a longer period of time. Was not one to use serums have just stuck to shampoo & conditioners but would definitely recommend this product

Rated 5 out of 5 by from Body, fullness hair [This review was collected as part of a promotion.] Applying the leave-in treatment directly to the scalp is a breeze because to its frothy nature. It gives my hair a slight boost of fullness at the roots without making it oily. My hair already has more body, and my scalp feels healthier. All things considered, I'm having a great time with this method and intend to continue using it to observe the longer-term effects. I heartily recommend it if you're struggling with hair loss and want a product that promotes a healthy scalp.

Rated 5 out of 5 by from Great addition to my regular routine! [This review was collected as part of a promotion.] I’ve been using the Nioxin Hair Thinning Serum as part of my daily routine, and I really like how light it feels on my scalp. The fresh, tingling sensation makes me feel like it’s doing something straight away, and it doesn’t leave any greasy residue. After a few weeks, my hair feels a bit stronger at the roots, and I’ve noticed less breakage when brushing. It’s a slow, patient process, but it’s become a simple step I look forward to because my scalp feels healthier and more refreshed overall.
